Archaeologists uncovered hidden inscriptions and graffiti left by medieval pilgrims on the walls of the Cenacle, the site of Jesus’s Last Supper in Jerusalem. The messages, etched centuries ago, provide valuable insights into the spiritual journeys and traditions of Christian pilgrims visiting the sacred site. The Last Supper is one of the most venerated events in the story of the Christian faith. The site of Jesus’s Last Supper itself likely originally held a synagogue. And now, a study published in Studium Biblicum Franciscanum has revealed that some of those pilgrims left messages behind on the very walls that surround this sacred site.
